'5 Claims. 1

This invention relates broadly to fastening devices, and more particularly to fastening means for insulators.

A main object of the invention is to provide a novel and improved structure for fastening two members together, said structure being very simple to manipulate and providing a reliable connection. I

A further object of the invention is to provide an improved fastening structure particularly adapted for connecting an insulator to a fence post, as in electric fences, or the like.

A further object of the invention is to provide a novel and improved fence post and insulator to be used therewith for employment in electric fences, the insulator being readily attachable to the post and providing an efiective securing means for the fence wire.

A further object of the invention is to provide an improved post and insulator structure for an electric fence,- said structure being very inexpensive to manufacture, easy to install and efllcient in performance.

Further objects and advantages of the invention will become apparent from the following description and claims and from the accompanying drawin wherein:

Figure 1 is a side elevational view of an insulator according to the present invention.

Figure 2 is a rear end view of the insulator of Figure 1.

Figure 3 is a front nd view of the insulator of Figure 1.

Figure 4 is a detail view, partly in cross-section illustrating the method of locking the insulator of Figure 1 to a fence post according to this invention.

Figure 5 is a perspective view showing an electric fence wire secured to an insulator and fence post in accordance ,with the present invention.

By way of example, an illustrative embodiment is disclosed wherein the fastening means of the present invention is employed to connect an in sulator to a fence post in an electric fence in-- Extending axially from the rear end of body' portion I2 is a horizontally flattened and laterally reduced neck element l8 carrying a circular head Referring to Figures 4 and 5, 20 designates afence post, which may be made of suitable rigid material such as steel angle iron. The bottom end of post 20 is tapered to a point 2| to facilitate driving the post into the ground.

One of the flanges of post 20 is formed with a plurality of openings 22, each opening comprising a large substantially circular upper portion 23 and a smaller substantially circular lower portion 24, said circular portions being connected by a vertical slot portion 25. Upper portion 23 is just large enough to receive head member IQ of the insulator H. Slot portion 25 is just large enough to provide clearance for neck element l8 when said neck element is in a vertical position. Lower portion 24 is just large enough to accomm'odate neck element 18 and to support it in the horizontal position thereof shown in Figure 4.

In this position the insulator is restrained against either end-wise or vertical movement with respect to post 20. I

In assembling the fence structure the insulator ii is positioned in a selected opening 22 in the manner shown in Figures 4 and 5, the head member l9 being passed through the upper opening portion 23, the neck portion 18 being passed vertically through slot portion 25 and being rotated to horizontal position in lower opening portion 24. The fence wire 26 is positioned in slot i3 rearwardly of th aligned bores 16 and I1 and a headed pin 21 is passed through said aligned bores. Wire 26 is thus secured against removal from slot l3 and acts at the same time to prevent the insulator from being rotated to a disengaging position.

Although th fastening structure disclosed herein is shown specifically in connection with a fence post and insulator it may also be employed to secure various other parts together within the spirit of the present invention. Although a specific embodiment of a combination of an insulator and fence post for electric fences has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore it is intended that no limitations be placed on the invention other than as defined by the scope oi the appended claims.

What is claimed is:

1. An electric fence insulator comprising a cylindrical body member having a slot formed in one end thereof to define a pair of projections, means'ior retaining a wire in said slot, a flattened neck member projecting axially from the other end of said body member, the width of said neck member being less than the diameter of said body member, and a circular head carried at the end of said neck member, said head being larger in diameter than the width of said neck member. e s

2. An electric fence insulator comprising a cylindrical body member having a slot formed in one end thereof to define a pair of projections, means for retaining a wire in said slot, a flattened neck member projecting axially from the other end of said body member, the width of said neck member being less than the diameter of said body member, and a circular head carried'at the end of said'neck member, said head being larger in diameterthan the width of said neck member but being smaller in diameter than the body member.

3. In combination, a fence post comprising an elongated rigid member having an opening formed therein, said opening comprising an upper substantially circular portion, a lower substantially circular portion of lesser diameter than said upper portion and a vertical slot portion connecting said upper and lower portions, an insulator having a flattened neck portion which is less in thickness than the width oi said slot portion and approximately equal in width to the diameter of said lower portion, one end said insulator being formed with a wire-receiving slot, said slot being substantially coplanar with said neck portion, said neck of said insulator being adapted to be seated in said lower circular portion of said opening with the width of said neck portion at right angles to said slot and means for securing a wire in said slot to prevent rotation of said insulator in said opening.

4. A fastening structure comprising the combination of a rigid member formed with an opening, said opening comprising an upper substantially circular portion, a lower substantially circular portion of lesser diameter than said upper portion and a vertical slot portion connecting said upper and lower portions, an element adapted to be secured to said rigid member, said elemeat having a body wider than the diameter of said upper circular portion. a flattened intermediate neck portion which is less in thickness than the width of said slot portion and approximately equal in width to the diameter oi said lower portion, and a substantially circular head which is less in diameter than said upper circular portion but greater in diameter than said lower circular portion, said body being formed with a recess said recess being substantially coplanar with said neck portion, said neck portion oi said element being adapted to be seated in said lower portion of said opening with the width or said neck portion at right angles to said slot, and means for securing an elongated member in said recess to prevent rotation of said element.

5. A fastening structure comprising the combination of a rigid member formed with an opening, said opening comprising a substantially large portion, a spaced and substantially smaller portion and a slot portion connecting said large and smaller portions, an element adapted to be secured to said rigid member in said opening, said element having a body wider than the diameter of said larger portion of said opening, a listtened intermediate neck portion which is less in thickness than the width of said body and approximately equal in width to the diameter of said smallerportion of said opening, and an enlarged head which is less in diameter than. said larger portion of said opening, but greater in diameter than said smaller portion of said opening, said element being adapted to be seated in said smaller portion with the width 01' said neck portion at right angles to said slot portion, and means for securing an elongated member to said body to prevent rotation of said element in said opening.
